Abstract

The invention discloses a green, environmentally-friendly, fireproof and waterproof light building material, and relates to the technical field of heat preservation building material production and processing. The green, environmentally-friendly, fireproof and waterproof light building material is prepared from the following components in parts by mass: 60 to 80 parts of modified expanded perlite,20 to 35 parts of cement, 20 to 28 parts of water, 10 to 16 parts of a bagasse powder, 8 to 12 parts of dry sludge, 5 to 10 parts of sodium fluosilicate, 2 to 5 parts of calcium stearate, 5 to 10 parts of an additive, 0.5 to 1 part of polypropylene fiber, 1 to 5 parts of a putty powder, 3 to 5 parts of a wollastonite powder and 2 to 3 parts of calcium formate. The expanded perlite insulation board prepared in the invention is excellent in fireproof performance, light in weight, high in strength, low in heat conductivity coefficient, high in compatibility with a bonding layer and an anti-crackprotection layer of an insulation system, simple and convenient in integral processing technology and obvious in effect, the processing cost can be reduced, the capacity is improved, and the requirements of environmental protection and high quality are met.

Description

Technical field: [0001] The invention relates to the technical field of production and processing of thermal insulation building materials, in particular to a method for preparing a green, environmentally friendly, fireproof and waterproof lightweight building material. Background technique: [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. [0003] The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insu...
